In addition, interest on home equity debt can also be deductible. Home equity debt essentially includes any other loan that is secured by your main home or second home. A lower borrowing limit of $100,000 for most taxpayers or half that for married taxpayers filing separately applies to home equity debt. What counts as mortgage interest? The portion of your monthly payment that goes to interest clearly counts as deductible mortgage interest for these purposes.
You can also generally deduct interest on home equity debt of up to $100,000 ($50,000 if you're married and file separately) regardless of how you use the loan proceeds. For details, see IRS Publication 936: Home Mortgage Interest Deduction. If you own rental property and borrow against it to buy a home, the interest does not qualify as mortgage interest because the loan is not secured by the home itself. 2  Interest paid on that loan can't be deducted as a rental expense either, because the funds were not used for the rental property.
